Making shoes

So i just have been experimenting making shoes.  My first shoe design was brown paper stripped out and braided into very long braids then glued into a sole shape.  I used two layers of this braided sole then stitched on a heel fabric and a toe fabric.  I used a grommet maker to pass a lace through the ankle and toe fabric.  It is a great design.  I’m not sure how sturdy they are but would be fun to reproduce with maybe a molded sole.
I now am going to embark on some moccasin type shoes made of bike tire.  I have tons of bike tire and just use heavy duty thread.
